◉ Matter
Answer: A substance or a mixture of substances


◉ Substance
Answer: A form of matter that has a specific, universally constant
composition and distinct properties, such as color, smells, and
taste


◉ Solid
Answer: Particles that are held close together in an orderly
fashion with very little freedom of motion


◉ Liquid
Answer: Particles that are close together, but are not held rigidly
in position; they can move around within the liquid


◉ Gas

, Answer: Particles that are separated by distances that are very
large compared to the size of the particles. Conforms to the shape

◉ Homogeneous Mixture
Answer: A mixture in which substances are evenly distributed
throughout the mixture (sugar and water)


◉ Heterogeneous Mixture
Answer: A mixture in which different materials can be
distinguished easily (sand and iron)


◉ Density
Answer: Mass per unit volume (Quantitative)


◉ Physical Property
Answer: A property of a substance that can be observed and
measured without changing the identity of the substance (you can
still change its state, liquid, gas, or solid)
